Description

Technical Field

[0001] This application belongs to the field of building technology, specifically relating to an asphalt mixing and stirring device. Background Technology

[0002] In the current sample asphalt mixing process, traditional feeding hoppers are mostly fixed structures. Although they can complete the mixing of sample asphalt, there are significant defects in the feeding process.

[0003] Fixed feeding hoppers typically rely on gravity for feeding, meaning they are designed with both mixing and feeding ports. However, these hoppers require the feeding port to be sealed during mixing to prevent leakage. Therefore, the overall sealing requirements are high. Furthermore, because the sample asphalt has high viscosity, the outlet is prone to sticking to the feeding point. Over time, this can cause the feeding port to jam or become blocked when switching between feeding and mixing modes. The overall structure is complex and maintenance costs are high. Utility Model Content

[0004] To address the shortcomings of the prior art, this application provides an asphalt mixing and stirring device. Through the design of the feeding mechanism, the mixing mechanism is rotated by a control component, thereby pouring out the asphalt in the feeding mechanism. This structure only requires one outlet for mixing and feeding, avoiding jamming or blockage at the feeding outlet. The overall structure is simple, the feeding operation is convenient, and the difficulty of subsequent device maintenance is reduced, thereby effectively reducing maintenance costs.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0030] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0031] Example 1:

[0032] Please see the appendix Figure 1 The present application discloses an asphalt mixing device, which includes a support mechanism 1, a material feeding mechanism 2, a mixing mechanism 3, and a material unloading mechanism 4.

[0033] The two sides of the feeding mechanism 2 are movably connected to the two sides of the support mechanism 1 for loading the mixed raw materials for preparing asphalt; the mixing mechanism 3 is arranged opposite to the feeding mechanism 2 and connected to the upper end of the support mechanism 1. The mixing mechanism 3 is used to enter the feeding mechanism 2 and mix the raw materials; the feeding mechanism 4 includes a control component and a feeding component 42. The feeding component 42 is located on the feeding mechanism 2, and the control component is connected to the feeding mechanism 2 for controlling the rotation of the feeding mechanism 2 to pour the material.

[0034] In this embodiment, the asphalt mixing device is prepared as follows: the raw materials for asphalt preparation are poured into the feeding mechanism 2, and the mixing mechanism 3 is started. The mixing mechanism 3 thoroughly mixes the raw materials in the feeding mechanism 2. After mixing is completed, the control unit of the feeding mechanism 4 controls the feeding mechanism 2 to rotate with the support mechanism 1 as the point until the mixed raw materials are discharged from the outlet of the mixing point to the feed member 42, which uses the principle of gravity to discharge the material. After the discharge is completed, the control unit again controls the feeding mechanism 2 to rotate to a position opposite to the mixing mechanism 3, thereby completing the mixing and discharge action.

[0035] In this structure, the mixing and pouring share a single inlet, making the overall material feeding mechanism 2 simple and practical. When pouring, the material feeding mechanism 2 is rotated directly, and the mixed raw materials can flow from the material feeding mechanism 2 to the feed inlet 42 based on the principle of gravity. The pouring operation is easy, and this structure can avoid jamming or blockage at the discharge port, thereby reducing the difficulty of subsequent device maintenance and effectively reducing maintenance costs.

[0036] In some embodiments, the control unit includes at least one motor 41A, the drive end of which is driven by the material feeding mechanism 2. This configuration automates the material feeding process using the motor 41A. The rotation speed and angle of the motor 41A can be set before device assembly, facilitating manual operation. A start button can be provided to manually control the start and stop of the motor 41A according to actual conditions, ensuring flexibility in asphalt preparation. Alternatively, two motors 41A can be used to synchronously drive both sides of the material feeding mechanism 2, improving the force balance during rotation and material feeding, and further optimizing stability during feeding.

[0037] In other embodiments, please refer to the appendix. Figure 2 The control unit includes at least one handle 41B, which is connected to one side of the feeding mechanism 2. Since this device is used to prepare sample asphalt, the amount to be mixed is relatively small. Therefore, the handle 41B is directly provided, and a force is applied to the handle 41B in the direction of the feeder 42 to achieve manual feeding. This operation is simple, quick, and flexible, reducing resource consumption. Alternatively, two handles 41B can be provided, i.e., located on both sides of the feeding mechanism 2, allowing feeding from multiple positions or multiple people to apply force simultaneously, increasing the versatility of feeding methods.

[0038] In some embodiments, such as Figure 2 The support mechanism 1 includes an elevation platform 11, which is located below the material placement mechanism 2. A material guide 42 is connected to the elevation platform 11, and the material guide 42 forms an angle α with the plane of the elevation platform 11. Preferably, the angle α is 25°-45°. This setting facilitates the material guide 42 to the corresponding position, ensuring smooth material pouring. The elevation platform 11 increases the range of motion for receiving the mixture flowing from the material guide 42, improving the convenience of receiving materials and accommodating various sizes of receiving tools, thus offering strong adaptability.

[0039] In some embodiments, the material storage hopper 21 is formed by a hollow frustum and a hollow cylinder connected from bottom to top. With this configuration, the lower part of the material storage hopper 21 is shaped like a hollow frustum. During the pouring and rotating process, the outer wall of the hollow frustum shrinks towards the direction of loading the mixed raw materials, preventing jamming with the lifting platform 11 during pouring and ensuring smooth pouring. Simultaneously, the upper part of the material storage hopper 21 is combined with a hollow cylinder, making the overall structure more compact, ensuring structural stability, and simultaneously meeting the requirements for large-capacity loading and mixing.

[0040] In some embodiments, please refer to the appendix. Figure 2 The mixing mechanism 3 includes a rotating component 31, a mixing component 32, and a lifting cylinder 33. The lifting cylinder 33 is connected to the support mechanism 1, and its drive end is connected to the rotating component 31 to drive its lifting motion. The rotating component 31 is driven to the mixing component 32. Specifically, the mixing mechanism 3 operates as follows: when the raw materials are placed into the storage bin 21, the mixing component 32 is positioned above it. When mixing is required, the lifting cylinder 33 lowers the mixing component 32 into the storage bin 21 until it reaches a certain position and stops descending. Then, the rotating component 31 is activated, causing the mixing component 32 to rotate and mix within the storage bin 21. The mixing time and speed can be set according to actual conditions. After mixing is complete, the rotating component 31 stops rotating, and the lifting cylinder 33 is activated, raising the mixing component 32 to its initial position, thus completing the action of the mixing mechanism 3. This design prevents the mixing component 32 from obstructing the rotation and pouring of the storage bin 21, ensuring smooth pouring and enabling independent operation of the mixing and pouring functions.

[0041] In some embodiments, the shape of the agitator 32 corresponds to the shape of the feeding hopper 21; the agitator 32 is a perforated agitator 32. Through this configuration, the agitator 32 and the feeding hopper 21 are adapted to each other, so that the agitator 32 can fully contact the mixed raw materials in the feeding hopper 21, and combined with the perforated agitator 32, the mixing is more thorough, achieving higher mixing efficiency.

[0042] Example 2:

[0043] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 3 The feeding mechanism 2 in this embodiment includes a feeding hopper 21 and a heating unit 22. The feeding hopper 21 has a functional cavity 213, and the heating unit 22 is disposed in the functional cavity 213. The heating unit 22 is used to control the temperature of the contact surface between the feeding hopper 21 and the mixed raw materials. The heating unit 22 can be implemented using any of the following methods: an existing electric heating wire, a ceramic heating plate 423, or a heat-conducting oil heating coil. Preferably, a heat-conducting oil heating coil is used for heating.

[0044] In this embodiment, the feeding mechanism 2 adopts a heating part 22, which can effectively distribute heat evenly around the wall of the feeding barrel 21, ensuring good fluidity throughout the stirring process. The heat transfer oil can be recycled, which can effectively reduce heating costs.

[0045] Furthermore, due to the high viscosity of asphalt, heating reduces its viscosity, significantly decreasing the amount of residual material during the feeding process and allowing it to flow out of the feeding hopper 21 at a more stable flow rate and speed. Cleaning also becomes relatively easier; simple tools such as scrapers and brushes can more easily remove residual asphalt, reducing cleaning time by more than half. This also reduces potential damage to the feeding mechanism 2 caused by cleaning difficulties, extending its service life.

[0046] Please see Figure 4 The material storage bin 21 has symmetrical connecting parts 211 on both sides. The connecting parts 211 are connected to the control parts and have notches 212. The support mechanism 1 has a limiting block 12 corresponding to the notch 212. The limiting block 12 is used to limit the rotation direction of the connecting parts 211, so that the discharge port of the material storage bin 21 can only tilt and rotate in the direction of the feeding part 42, thereby ensuring the stability of the operation of the material storage bin 21 and avoiding the situation of reverse tilting and unloading.

[0047] Example 3:

[0048] The difference between this embodiment and Embodiment 2 is that, please refer to... Figure 5 In this embodiment, the feeder 42 includes a body 421, a baffle 422, and a heating element 423. The baffle 422 is connected to both sides of the body 421, and the heating element 423 is disposed at the lower end of the body 421. The heating element 423 is used to control the temperature of the body 421. Preferably, the heating element 423 can be a small electric heating element. This configuration allows the body 421 to be heated, preventing the asphalt from flowing smoothly due to low temperature during the pouring process, thus improving the smoothness of the pouring. It also prevents asphalt from sticking to the body 421 and the baffle 422, effectively improving the ease of cleaning.

[0049] In some embodiments, the feeder 42 further includes a rock wool insulation layer 424, which is wrapped around the heating element 423. Preferably, a 50-100 mm thick rock wool insulation layer 424 is wrapped around the outside of the heating element 423. The rock wool insulation layer 424 is a high-quality inorganic fiber insulation material with a thermal conductivity as low as 0.03-0.045 W / (m·K), which can effectively prevent heat from dissipating into the surrounding environment, reduce energy consumption, and protect operators from high-temperature burns, thereby improving operational safety.
